ELECTROLYTE SUITABLE FOR LITHIUM PRIMARY BATTERY

The present invention relates to an electrolyte suitable for a lithium primary battery. In order to solve the problems of poor safety performance, high-rate discharge and poor discharge performance of electrolytes of the existing lithium primary batteries under a high-temperature condition, the electrolyte of the present invention comprises an electrolyte lithium salt, an additive, and an organic solvent, wherein the electrolyte lithium salt comprises one or more of lithium trifluoromethanesulfonate, lithium bis(trifluoromethanesulphonyl)imide, lithium difluorophosphate, and lithium difluoro(oxalato)borate; the additive comprises one or more of (2-trimethylsilylethyl)2-cyanoacetate, diphenyldimethoxysilane, and citraconic anhydride; and the organic solvent comprises a carbonate solvent and a glycol ether solvent. According to the present invention, by means of a selective combination of the electrolyte lithium salt, the additive, and the solvent, normal-temperature discharge can be met when the electrolyte in
